Title: Reduced holdup in catalytic reactor
Inventor: BUTTKE ROBERT D
IPC: C10G45/18
Filed: 1991-04-30
Abstract: A reactor for refining resid includes an elongated vertical vessel containing a bed of catalyst which is expanded or ebullated by a liquid/gas mixture.  The mixture rises in an updraft through the bed and then is recirculated with an increased velocity by an ebullating pump.  To reduce gas holdup of the ebullated bed and to promote a more uniform flow, the gas is entrapped by two cascaded stages of baffles which have an internal conical shape to guide, direct, and entrap the gas.  One of these two stages has a shape which creates a countercurrent in the flowing liquid to deflect any catalyst particles which might otherwise be elutriated by the increased velocity.

Title: Optical amplifier
Inventor: PFEIFFER THOMAS
IPC: H01S3/06
Filed: 1991-05-01
Abstract: ABSTRACT                  Optical Amplifier Conventional optical amplifiers for the amplification of optical signals propagating in an optical waveguide show a single light source (5) for the production of a pump light, by means of which an active laser substance (2) is excited to a first energy level above its upper laser level.     According to the invention, another light source (7) is present, through whose pump light the active laser substance (2) is excited to a second energy level that is above the first energy level.  In that case, spontaneous emission between the laser levels of the active laser substance (2) is suppressed in favor of induced emission. (Figure 1)

Patent CA-2052454-A1 (CA)
Title: Laser driver with plural feedback loops
IPC: H01S5/0683
Filed: 1991-09-30
Abstract: A laser driver circuit applies pulses of current to a laser diode to activate the diode to emit pulses of radiation suitable for operation of a laser printer. A field-effect transistor (FET) is serially connected with the laser diode and with a feedback resistor for applying the current pulses, the feedback resistor serving as a source of a feedback signal indicative of the magnitude of current flow. A photodetector senses radiation outputted by the laser diode and emits an optical feedback signal representative of radiated power of the laser diode. A combiner circuit, responsive to an input digital command signal, combines the current feedback signal and the optical feedback signal with the command signal to generate a drive signal for activating the FET. The combiner circuit includes an input section in which a current source powers a differential amplifier operating in a switching mode in response to the command signal a driver section wherein a current source powers a differential amplifier operating in a linear mode and connecting between the input section and the FET, and a threshold section connected to the input section for establishing a threshold current level in the drive signal which activates the FET.
